Big Head Mode 
     For  the  bikers to have larger heads, simply type "big heads" at
the main menu.

Quick Recovery
     Press  the [TAB] key to reset your player immediately on the bike
to  continue racing. This is extremely helpful if you're racing others
and you fall. You don't have to wait for the cinematics of you falling
or waste time getting back on the bike.

Rainbow Studios
     When  playing,  press  [ALT]+[TAB]+[A]  like  you meant to switch
screens.  When  you  open  up  MCM2  again, the ground will be Rainbow
Studios' pattern. To remove this, simply restart your race.

Nosedive Wheelie
     To  do  a  nosedive wheelie, gain at least a top speed of 85 MPH,
then select a small jumping ramp with a clear landing space to perform
this  stunt.  Before  you land, lean forward into the handlebars until
your bike is completely vertical. Hold the brake button and you should
be  able to keep your rider on the bike for one of the coolest tricks,
a nose wheelie, which is a cross between a vert twist and a handstand.
